After decades of fast-paced technical advances, optical/infrared (O/IR) interferometry has
seen a revolution in recent years:▪ The GRAVITY instrument at the Very Large Telescope …

Constraining planet formation based on the atmospheric composition of exoplanets is a
fundamental goal of the exoplanet community. Existing studies commonly try to constrain …

Abstract We present JWST Early Release Science coronagraphic observations of the super-
Jupiter exoplanet, HIP 65426b, with the Near-Infrared Camera (NIRCam) from 2 to 5 μm …

We present K-band interferometric observations of the PDS 70 protoplanets along with their
host star using VLTI/GRAVITY. We obtained K-band spectra and 100 μas precision …

Isotope abundance ratios have an important role in astronomy and planetary sciences,
providing insights into the origin and evolution of the Solar System, interstellar chemistry and …

Context. Methods used to detect giant exoplanets can be broadly divided into two
categories: indirect and direct. Indirect methods are more sensitive to planets with a small …

Observations of exoplanet atmospheres have shown that aerosols, like in the solar system,
are common across a variety of temperatures and planet types. The formation and …

The present-day envelope of gaseous planets is a relic of how these giant planets originated
and evolved. Measuring their elemental composition therefore presents a powerful …

Abstract Using the Keck Planet Imager and Characterizer, we obtained high-resolution (R∼
35,000) K-band spectra of the four planets orbiting HR 8799. We clearly detected H 2 O and …

Precise measurements of chemical abundances in planetary atmospheres are necessary to
constrain the formation histories of exoplanets. A recent study of WASP-127 b, a close-in …
